test case

According to
http://msdn.microsoft.com/en-us/library/system.diagnostics.datareceivedeventargs.data.aspx
, after the redirected output (Process.OutputDataReceived) / error
(Process.ErrorDataReceived) have been closed, an event should be raised with
DataReceivedEventArgs.Data set to null. CruiseControl.Net 1.4.2 relies on this
to detect that is has read all available output data. Mono does not raise this
"additional" event (it correctly sends populated DataReceivedEventArgs while
the process is working). This bug is present on Windows (Mono 2.0.1) and Linux
(Mono 2.0.1 and SVN r121581 ).

A test case program is attached.

Expected output (run on MS.Net):

started, waiting for keydown
out: Mono JIT compiler version 2.0.1 (tarball)
out: Copyright (C) 2002-2008 Novell, Inc and Contributors. www.mono-project.com
out:    TLS:           normal
out:    GC:            Included Boehm (with typed GC)
out:    SIGSEGV:       normal
out:    Notification:  Thread + polling
out:    Architecture:  x86
out:    Disabled:      none
out: ===received null
error: ===received null
process exited

Actual output (run on Mono):

process exited
